'l'oall 'whom it may concern:

Be it known that I, NrELs C. BRoNDER- BLEV, acitizen of the UnitedvStates, residing at Minden in the county of Kearney and State ofebraska, have invented new and useful Improvements in Leaf-SpringiDevices calledleaf-spring oilers have'been ati devised for attachment tosuch springs whereby a small amount of lubricant is con` stunt-ly fed tothe leaves thereof to prevent "this squeakin My invention relates tothis class o'f attac ment, and its primary object is to cliptheattachment to the'spring in such a manner that it will not become lostoil' and will'not creak., VThis object is carried out by the specificconstruction of parts hereinafter more fully described and claimed and`as shown in the drawings wherein i.

Figure-1 is a perspective view of part of a semi-eliptical spring withthis attachment ap lied.

ig. 2 4is a transverse section on an enlarged scale, taken on about theline 2-2 of Fi "1.

li 3 is a plan view of the blank of feltl or otk er absorbent before itis put in place. Fig. 4 is a still further enlarged detail of Fig. 5 isasectional view of a modification. We are not concerned with the shape ofthe spring S, nor its details of construction Jexcept that it is made upof leaves, and of l most which I`have lettered L in the these we areinterested only in the u perrawings. In Fig. 1 the attachment is shownas applied to the inner side of a semi-eliptical spring, but it isobvious that it could' bo applied to outer or upper side of a full-`eliptical spring. Its point of attachment is y' immaterial `but bypreferencerit is placed where its sides extend down past several of theleaves as shown. c

.The casing is of substantially inverted U.

Yas felt, the b ankl of which is illustrated at 4 in Fig. 3, which viewshows that it is' provided near its center with :t long slot` 5.

This absorbent is somewhat thicker than the width of the flanges so thatwhen in place it projects beyond them toward the interior of thecasing,- and obviously it bears against Patented Jaa. 8,1918.

the edges of the'several leaves of the spring.

TheA oil cup, whose details are best seen in' Fig. 4, comprises Vatubular body 7 whose lower end is reduced at 8 and whose upper end risesthrough a hole in the top plate and above the same and is'threaded forYthe reception of a binding'nut 9. While the in-y ternal construction ofthis' oil cupv is not essential, I will state that as shown it comprisesa bore having an expansivespring 10 and anoutlet opening 11 from oneside of its lower end, the upper end of the bore being reduced as at 12.Upon thespring and beneath the reduced end stands a ball'` 13, normallyclosed upward against the re-v duced end sopas to keep out dust anddirt. lVhen the tip of an oil can is inserted through the end 12, theball is depressed, oil is poured into the cup. passes the ballrandthrough the spring, and flows out the outlet 11 onto the absorbent 4.

A striking feature of my invention is the use of a retainer -or clip forholding the atachment on the vupper, leaf L o'f a spring. This retaineris made of Spring metal, and it has a flat body 20 with its ends 21turned down and bent inward slightly at 22 so as to hook around theedges of theleaf L and between it' and the next `adjacent leaf.l

the felt has been put into the casing or hous-4 ing the retainer and oilcup are inserted and borne upward, and the body ofthe oil cup,

is passed through the -slot 5 in the absorbent and .upward through a hole in the top plate 1, 'and the 'nut 9 applied. Tightening up on thisnut draws the parts together, and draws theretainer. or clip upward soas toholdthe absorbent'against the top plate and between its flanges,and thereafter a few additional turns gwen to the nut 9 raises thecenter of the clip or retainer while its remaining portion is held fromrising b contact with the l'iiee ol' the absorbent. 'lille result isthat Ilie body 20 of the retainer is caused to be 4arched at its centerso that its ends nre runted inward und the extremities 22 are forcedunt-ler the leaf L so that the whole is elippeil upon the leaf quiteforcibly and held against slipping. ln the application of this devicetio n wiring, before tension .is ,up lied attarlunent een not slip orcreep, and will notget out o l pl;ire or beeo'nie lost off the -wiring,l-`ron| linie lo linie oil introduced into lulul oil up :intl [lows do illie absorb eut, and as' will he eloar this oil is fed slowlyr to the.edges of the ,several loaves ot the spring so that the lutter will notSqueak. I lo uot wish tobe liniiled further thun as Set forth in the.rla'ung below, and the pro ioitionsF sizes andnnnterials ot' ports areot ierniso unimportant..

[u the nmdilcation shown in Fig. 5,.thr.. mineras-ing, retainer. andabsorbent. et with its slot 5 are employed,- but the top plate l of theeasing is pierced with .ahole 11 orei the slot, and untlerlvingt-liishole und worli- .ing within snid slot is a. leaf spring. l0 whosenoi-unil tendent- 5I is to close the hole. lzlowever, when an oil can isbrought into use and its tip inserted through the hole us indicated iiili`g. `5, the spring is bent; downward und oil may flow past it; andthrough the slot :'i in a manner alreudy described. qIfhe tubular oilenp is now replaced by n bolt. 7 pussing through .the parts und hnifingits lower eufl 8 reduced and upset or riveted inside lthe retainer, anda nut9 engages the threaded upper end'of this bolt und bears on the topplate 1 to hold all parts in close eontnc W'hnt is claimed iis new isz-1i The herein described leaf spring oiler comprising n sheet-metal bodyU-sliaped in eross section, bent into an u por ortion to orerlie this srin und two c ep'ent ing arms to pass by tie ec ges of the severalleaves thereof, ull portions having side thin es,an absorbent; sheetmounted within sai body and thiclcer thou the width of said finngcs, aietiiining plate of spring nietnl underlying the upper portion of saidabsorbent und having 'its ends bent dowi'iward and its extremitiesturned inward, nu oil cup whose body` passes through the top. plute ofsaid body lportion and the upper part of seid nbsorb-" ent, whose lowerend is secured to the center ol said retainer, :ind whose upper end isexternally threaded, and n nut on 'aid threiided end lfor drawing theoil cup :ind the center .o'f the retainer upward whereby the retainer isarched and itsI ends canted inward, (or the purpose set forth.
